Name: _________ KEY ______________________________ Date: ____________ WKST #17: Unit 12 Review Sheet (20 points) Period: ___________ 1. Given the reaction and rate data below: A (g) + B (g) + C (g) D (g) a. Write the rate expression. rate = k [A] 1 [B] 2 [C] 1 b. What is the value of the rate constant? c. What is the rate of reaction 5? rate = k [A] 1 [B] 2 [C] 1 rate = k [A] 1 [B] 2 [C] 1 0.50 = k [.10] 1 [.10] 2 [.10] 1 rate = 5000 [.30] 1 [.30] 2 [.30] 1 k = 5000 1/ M 3 s rate = 40.5 M/s 2. What can be concluded about the rates of the forward and reverse reactions when a system is in equilibrium? What will happen to the concentrations of the materials in the equilibrium system? At equilibrium, the rates of the forward and reverse reactions are equal. The concentrations of the products and the reactants will not change. This is an example of dynamic equilibrium. 3. Define each type of equilibrium and give an example.
